OpenGL 3D Game Tutorial 14: Simple Terrain

LWJGL tutorial series on how to create a 3D Java game with OpenGL!

This week we program a terrain renderer and generate a simple flat terrain!

Full code download (try doing the tutorial first though!):

Common Problems:

-If you can't see the terrain make sure your camera is in the right position! It needs to have a y position of above 0, and if you still can't see the terrain then try turning the camera around by setting the "yaw" to 180.

-Make sure that you're starting and stopping the *terrain shader* (and NOT the static shader program) before and after rendering the terrain in the MasterRenderer's render() method.

-If the texture on the terrain only looks good in one corner then try adding these 2 lines into your loadTexture method before returning the texture's ID:

I've created terrain before, but I like how you organize your code. How data is managed is also a subject I seldom see in tutorials, yet it is very important.

Excellent tutorial! Everything has worked perfectly so far, but in this episode I struggled a bit to see the ground. Like said, it was the camera position that could have solved the problem, but also positioning the terrains differently would make them show. Like this:

Terrain terrain = new Terrain(-1, -1, loader, new
Terrain terrain2 = new Terrain(0, -1, loader, new

I hope i'll hepl someone with my comment: After dancing around the computer i tried just to move my camera a lot more in a different positions and i'vo found my terrain. Also i got a bit bigge rpicture before that. Anyway i'm happy like a little child that everything's working! Thanx man for great tutorials. I've started to learn java little less than 2 months ago. from zero. All i knew was a couple web pages on html. And now following this tutorial i'm making A GAME ENGINE!! OMG!!! That's cool! So all it means that you are a really good teacher! Thanx once again!!

i still have endless amounts of fun setting FOV to 170 and watching everything stretch and warp by at lightspeed XD

Although I already know these things the videos help me compare your backend against mine, to develop a better api. Also your Development log video diary things are very entertaining. Thanks!

a small typo got me hanging around for some time but now its resolved ^^
i always have to watch at 0.5 speed because i can't follow along that fast but you explain everything very good, thank you :D

[Joern]

Very nice tutorial! Thanks so much, you are so talented!!!

[jonatanla]

Gracias por estos asombrosos vídeo tutoriales, eres genial! :D

[skittles]

Ah, this is the tutorial I've been waiting for.

[itay]

Awesome tutorial! Keep this amazing work!

for now i'm making a 2d game, but when i finish it, i'll be doing a 3d one with the guidance of this tutorial series. For the terrain, i'll try a procedural generation of blocks, just like Minecraft.

edit: stupid mistake one of the variables was called textur not texture

[iJoemo]

If the tiles are repeated with large black margins surrounding them, check that the dimensions of grass.png are powers of 2, e.g. 128x128, 256x256, 512x512 etc.

[buffetize]

Thnx for the tutorial. This is Awesome!

How did you define your "whole terrain. When I rendered my terrain, I only see 1/4 of the world covered with the terrain. I found that out when I added in the sky box.

[MohammedPlaysMC]

All looks good, got 2 trees, my terrains, also set the sun to be 200 blocks high :D

[xekplugins]

just want to say thank you. brilliant job.

[dbejarcaballero]

How do you make appear the tree in the middle of both the textures?

[cosmic_gate]

I'm attempting to create your terrain "package" as a project in Visual Studio (C++) and then implement the procedural generation you've got in the other tutorial. Wish me luck! :P
